Due to the shear instability the amplitude of the velocity increases during 1 year before the moment of reversal of the global magnetic field polarity (RGMFP) for an arbitrary latitude. It reaches a maximum at RGMFP and decreases in the next year. When 蠅 A > 0, then the amplitudes of ...
All three components contribute to the reversal of magnetic polarity. The percentage of contribution from each component is different for different solar cycle. Our results also show that the sunspot number is positively correlated with the lower-latitude open magnetic flux area, but negatively ...
We present here the data to illustrate the viability of the method to produce a pattern similar to the sunspots butterfly pattern seen during a magnetic pole reversal. Assume that the magnetic moment M is pointing in a x-y-z coordinate system having a set of values (x, y, z) = ...
根据第二段第二句“To understand the magnetic field’s reversal, first, it’s important to be familiar with the solar cycle.(要了解磁场的反转,首先,熟悉太阳周期很重要)”可知,太阳磁场和太阳(活动的)周期有着密切的联系。故选B。 (3)题详解: 推理判断题。根据第四段第一句“During solar minimum,...

Before the polarity reversal at 776 ka, as the magnetic reconnection occurs at high latitudes, a pair of strong NBZ-sense FACs and a pair of weak Region-1-sense FACs emerge near the north pole, similar to today's FACs pattern under northward IMF conditions (Ganushkina et al., 2018). ...
Earth's magnetic poles also flip, but the interval between the reversals is much longer, averaging about every 300,000 years according toNASA Climate. The last pole reversal happened about 780,000 years ago. Solar cycle and sunspot activity ...
“During solar minimum, the sun’s magnetic field is close to a dipole (偶极子), with one north pole and one south pole, similar to Earth’s magnetic field. But as we shift toward solar maximum, the sun’s magnetic field becomes more complex, without a clear north-south pole separation...
Reversals of the solar magnetic dipole in the light of observational data and simple dynamo models Observations show that the photospheric solar magnetic dipole usually does not vanish during the reversal of the solar magnetic field, which occurs in each... VV Pipin,D Moss,D Sokoloff,... - 《...
